Chris,
Are you certain the dial calibration is really off on only 40 meters?
The KX1 frequency is controlled by the data sent to the DDS by the firmware.
If indeed the frequency is off by 685 Hz only on 40 meters, I would
suspect the firmware.
Replacement is the only fix - but you will have to
I guess using the word Dial may be misleading. I am simply trying to say
that on 40m the frequency that is being transmitted on is 685 hz higher than
what is on the display. This is only on 40m. The other 3 bands are pretty
accurate. The BFO and DDS menu options are set to 0.

Chris,
There is one thing that might produce the condition you state, and that
is if you have 40 meters set for USB. Tap the band button and see if
there is a u in the left of the display when the 7 digit is displayed.
The KX1 firmware controls both the transmit and receive frequencies.
Hi Don,
I am using my elmer's very expensive service monitor to watch the frequency
that the KX1 is generating. I set the VFO to a given frequency, type that
same frequency into the service monitor, then start a solid tune on the KX1.
There is a BNC cable connected between both devices.
Chris,
Let me be specific and succinct.
There are only 2 conditions that would cause that behavior.
1 - The KX1 is set to receive upper sideband on 40 meters.
2 - the firmware is sending incorrect data to the DDS.
Re-read my last email.
I do not question the accuracy of the service monitor, but
I took my XG3 to a friend who had a very expensive service monitor. To all of
our surprise, the XG3 was only a few Hz off up to about 15m and then up past
6M it was still 10hz off. This was surprising! What a great tool.
The reason I checked it was I was seeing an issue with my KX1 that
6 matches
